The contactor is the high-voltage switching relay that responds to a 24V signal from the thermostat or control board to energize the compressor and\/or condenser fan motor. When it fails, the result is typically a complete loss of cooling or heating — the outdoor unit simply will not power on, or it may hum and buzz without the compressor starting. Burned or pitted contacts and a failed coil are the most common failure modes.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole configuration | 24 VAC coil voltage | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 50\/60 Hz rated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part engineered to exact specifications for your unit.
